Melanopsis citharella elongata Locard; Wenz 1929a : 2693 [non Ferussac 1823 ]. Type locality. Ueken, Aargau, Switzerland. Age. Middle to Late Burdigalian ("Helvetian"). Type material. Paleontological Institute and Museum, University of Zurich, no number indicated. Discussion. Unlike the case of Melanopsis narzolina elongata Locard, 1878, this taxon was not synonymized by Wenz (1929a , p. 2693). Despite separating it from Melanopsis citharella , Wenz noted that this form is probably indistinguishable from the nominal species. After review of Locard's description and illustrations we fully agree with Wenz, and draw the taxonomic conclusion to synonymize Melanopsis citharella elongata with Melanopsis citharella . Hence, although it is a primary homonym, we avoid introducing another superfluous name.
